EUGENE, Ore. – The Arizona baseball team thumped Oregon, 14-5, on Saturday afternoon at PK Park as the Wildcats captured their fifth consecutive weekend series win, including a fourth in the Pac-10.

After spotting the Ducks a 2-0 lead through two innings, the Wildcats (29-25, 12-14 Pac-10) exploded for four runs in the third and four more in the fourth to take a commanding 8-2 lead.

In the third inning, Jett Bandy knotted the game at two runs apiece with a bases loaded single to left field. The Wildcats added a third run on a wild pitch and a fourth on Brad Glenn’s 16th career sacrifice fly to open up a 4-2 lead.

One inning later, the Wildcats again loaded the bases as Dillon Baird, who earlier extended his hitting streak to 21 games, stepped to the plate. Baird blasted a screaming line drive over the right field fence for his second grand slam of the season to extend UA’s lead to 8-2.

Arizona starter Kyle Simon, who allowed single runs in the first and second innings, pitched into the fifth running before turning the game over to the bullpen after 4 1/3 innings.

Oregon added a run on a fielder’s choice as Joe Allison entered in relief, but the right hander stranded three runners on base to help the Wildcats escape further damage and get out of the inning with an 8-3 lead.

Allison, who earned his fifth of the victory the season, pitched 1 2/3 innings of relief before running into a bit of trouble in the seventh, when he allowed a leadoff triple followed by an RBI double.

Cory Burns spelled Allison and gave up a single and a sacrifice fly before a double play ended the scoring threat.

Even so, the Ducks (14-41, 4-22 Pac-10) had cut UA’s lead to just 8-5 through seven innings. The Wildcats, though, had one more big inning left in their bats.

Like in their other big innings, the Wildcats loaded the bases in the eighth. Bobby Coyle scored in a wild pitch, and Bryce Ortega drove home a second run with a sacrifice fly to right field, pushing UA’s lead to 10-5.

With two outs, Baird lined a shot to right field that was dropped by Oregon right fielder Jett Hart, which allowed an unearned run to score.

That set the table for Jett Bandy, who went 3-for-5 on the day and drove in four runs, as the freshman third baseman hit a two-run, opposite field home run.

Brad Glenn, second on UA’s all-time home run list, followed with a solo home run to push his career total to 43 and give UA a 14-5 advantage.

Donn Roach pitched the final 1 2/3 innings, shutting out the Ducks over the span while allowing just one hit.

The victory puts UA within just one shy of reaching 30 wins and gives it a chance to sweep a third weekend series in the last four weeks.

The Wildcats will close out their 2009 regular season as they go for the series sweep on Sunday. First pitch is scheduled for Noon at PK Park.
